REQUEST FOR ADDITIONAL INFORMATION CONTAINMENT AND VENTILATION BRANCH GINNA NUCLEAR POWER PLANT RESPONSE TO GENERIC LETTER 2003-01 CONTROL ROOM HABITABILITY Generic Letter (GL) 2003-01 requested confirmation that your facilitys control room meets the applicable habitability regulatory requirements and that the control room habitability systems are designed, constructed, configured, operated, and maintained in accordance with the facilitys design and licensing bases. Item 1c of the GL requested that you confirm that your Technical Specifications (TSs) verify the integrity of the control room envelope and the assumed inleakage rates of potentially contaminated air. The GL further requested that if you currently have a P surveillance requirement (SR) to demonstrate control room envelope integrity, that you provide the basis for your conclusion that it remains adequate to demonstrate control room envelope integrity in light of ASTM E741 testing results. If you concluded that your P SR is no longer adequate, the GL requested that you provide a schedule for:

1. Revising the SR in your TSs to reference an acceptable surveillance methodology (e.g., ASTM E741), and

2. Making any necessary modifications to your control room envelope so that compliance with your new SR could be demonstrated. If you do not currently have a TS SR for control room envelope integrity, you were requested to explain how and at what frequency you confirm control room envelope integrity and why that method is adequate to demonstrate control room envelope integrity.

In your August 31, 2005, response to Item 1c of GL 2003-01, you stated that Ginna's TSs do not presently contain SRs to verify assumed in-leakage. You further stated that you recently verified that control room in-leakage is less than that assumed in the various analyses, (as stated in your response to Item 1a of GL 2003-01) and that the industry and the NRC are currently working toward resolution on Technical Specification Task Force (TSTF) 448, and a change to NUREG-1431 Standard Technical Specifications, which will answer these concerns (i.e., surveillance testing). You stated that you will continue to work with the NRC and industry in this regard and that, when appropriate regulatory guidance is available, you will consider submitting a license amendment request (LAR) based on that guidance.

Based on the above, it is requested that you submit an additional response to Item 1c of GL 2003-01 that includes the following:

1. An explanation of how and at what frequency you currently confirm control room envelope integrity and why that method is adequate to demonstrate control room envelope integrity (as originally requested in GL 2003-01, Item 1c).

Enclosure

2. A description of your plans to adopt TSTF-448, including a commitment to submit an LAR based on TSTF-448. The commitment should include a milestone for completion (such as within 90 days of the NRC's approval of TSTF-448). Or, in the event that you decide not to submit an LAR to adopt applicable sections of TSTF-448 into your TSs, the NRC staff requests that you provide: (a) an acceptable alternative that will ensure your control room envelope will be in compliance with the regulations; and, (b) in light of the commitment made by the majority of the respondents to adopt applicable portions of TSTF-448, explain your rational (including any potential hardship) for not committing to this industry standard.
